I was first immersed in ground penetrating radar (GPR) as a PhD student at Lulea University in northern Sweden in the mid-1990s, and I immediately fell in love with the technology. I love the ability it gives me to see hidden things so quickly and elegantly. I also love the notion that the equipment is […]

Thus far in my “insider story” (June, July, August 2020), I’ve described how, while working for Trimble in 1996, I first became aware of the technology, which was then still in development. After a jaw-dropping demo, I dove deep into evaluating the technology and its pioneering start-up company, Cyra Technologies, for a possible partnership with […]

It wasn’t quite an Indiana Jones adventure, but Alabama-based lidar consultant Robert Graham says it’s as close as he’ll ever come to the hair-raising exploits of an audacious archaeology professor. Graham’s adventure last April did not revolve around an ark, though it did include ancient ruins, small planes landing in grass fields, machetes hacking through […]

On a construction site, cement and concrete finishers, carpenters, framers, electricians, plumbers, flooring installers, and other trades people spend a lot of time taking measurements and interpreting blueprints before they can even start any of the specialized tasks they are trained and paid to perform. Until recently, it was not possible to project the blueprints […]

Traditionally, photogrammetry based on aerial images and stereo plotting, has been the realm of large mapping companies capable of affording the onerous ownership of planes and the high personnel cost of pilots, navigators and camera operators. The equipment used to convert the stereoscopic pairs into contour line maps cost hundreds of thousands of dollars and […]
